The quality of a fine screw is directly related to the wire that produces the screw. It is the inspection of the machine that produces the screws, which is conducive to safe and smooth production. Screws Socket Sets Manufacturers and wires have 1010A, 1018, 10B21, 45 gauge steel and so on.
The appearance of the formed screw is inspected to see if there are burrs, and the standard length of the formed screw is inspected.. What is the degree of lubrication of the screw? The salt spray test checks the rust time of the screw or how many hours it takes for the salt spray screw to rust. After that, the screw shipment was checked. Therefore, the energy screws that require hardness must be hardened. The method is to select the unqualified screws. Iron fine screws are usually punched with iron wire.
All rules pass, only rules stop. The final step is to perform color inspection and salt spray test inspections on the screws returned from electroplating. The raw materials are stainless steel SUS201, stainless steel SUS304, stainless steel SUS776, stainless steel SUS316, stainless steel SUS404 and so on. The raw materials are low-carbon steel, medium-carbon steel, and high-carbon steel. The raw materials of fine screws are iron and stainless steel. A good mold can make a good screw product.
Because many fine screws without hardening are easy to slip when using commercial materials, they may be broken easily. The screw manufacturer introduces how to check the quality of small screw products: The first inspection of the screw should start from the wire of the screw. The most fundamental factor of slippage and breakage is the inability of fine screw hardness. Ensure the quality of the screws
